STOVE.

Application filed April 30, 1928, Serial No. 274,093, and in Canada March 28, 1928.

This invention relates to stoves and more particularly to means for utilizing the heat from combustion by requiring the products of combustion to pass through control chambers before passing out through the smoke P pe A further object of my invention is to rovidea means for controlling the trave of the products of combustion in the control chambers. y y

A further object is to provide a means for permitting direct draft from the combustion chamber to the smoke pipe and a means of adj ustably controlling the same.

lVith the foregoing and other objects in view, as will appear as the description proceeds, the invention consists of the novel construction, combination and arrangement of co-operating elements as hereinafter more specifically set forth, claimed and shown in the accompanying drawings forming a part of the present application in which:

Fig. 1 is a perspective view of the preferred embodiment of my invention, parts being broken away to more clearly illustrate the interior construction.

Fig. 2 is a rear sectional view taken on the line 2-2 of Fig. 1, looking in the direction of the arrows.

Fig. 3 is a top plan view, the cover plate having been removed.

Fig. 4 is a front sectional view taken on the line -ill of Fig. 1, looking in the direction of the arrows.

Like numerals of reference designate corresponding parts throughout the dilferent views.

4 is the base portion preferably of rectangular shape in cross section which is pro vided with suitable feet as at 5 of any conventional design and is provided with an ash door 6, having a suitable draft control open- 1ng as at 7. Internally of this base portion 4, I provide a suitable grate 8, which may be of any conventional design, commonly used in a stove construction in which wood or coal may be used. The base portion 4 is interiorly lined with firebrick as at 9. If desirous, this base portion 4 may be of any conventional shape, such as circular or oval in cross section instead of rectangular in cross section as hereinbefore referred to.

The upper portion 10 of the preferred embodiment of my construction has outwardly extended side portions 10f". I The casing 10 is preferably made of castings. but I donot wish to thus limit myself,as the casing 10 and its associate parts may be made in any other desirable material and suitably put together to obtain the same results ashereinafter re ferred to. The casing 10 has a downwardly extended flange portion adapted to overlap the upper edge of the base portion 4, as at 11, and is suitably connected thereto by means of rivets or bolts 12. In thefront ofthis casing 10, I provide a tire door 14 which may be provided with a suitable draft check 15 of any conventional type. The casing 10 is provided with a cover 16, suitablyfitted over the top edge thereof, which cover may be pro vided with one or more removable lids 17.

Division walls lS extendupwardly in approximate parallel alignment with the base portion 4. The forward portion of each division wall 18 extends up higher than its rear portion this extra portion 18 acting as a baffle plate. 23 is a transverse partition, the lower edge of which rests on the upper edge of the rear portions of the division walls 18 and abuts the ends of the baffle plate portions 18. The transverse partition 23 extends up, andis suitably connected to the cover 16 in any desired manner, while the baffle plate portions 18 extend upwardly a pro-determined distance towards the cover 16, leaving a space therebetween through which the products of combustion from the combustion chamber 20 will pass while entering the control chambers 21. These control chambers 21 are the extended side portions of the casing 10 and are formed by the division walls 18, the front and side walls of the extended side portions 10', the bottom 19, cover 16 and the transverse partition 23 with the door associatedtherewith which will be referredto hereinafter.

24 are draft control doors, hingedly connected at their upper ends to the transverse partition 23. 25- is a control rod, having two outwardly extended lugs 26, each of which lugs is connected to its respective door by a link27, so that upon turning of the contml rod 25 by either handle 28, the door 24 can be opened or closed to control the flow of the products of combustion through the control chamber 21. 29 is a rack suitably retained on the casing 10 and is provided with a notched outer surface into which the inner face of the handle 28 may engage so as to retain the control rod 25 in various desired positions.

Rearwardly of the transverse partition 23, I provide a capping 30 over he rear portion of the division walls 18 This capping is arched so as to provide a deflector over the rear portion of the combustion chamber. The transverse partition 23 is provided with a rectangular opening 31. At op posite ends of the opening 31, I provide guides 32, in which a door 33 is slidably positioned. Attached to the upper end of the door, I provide a control member Elsi, having a ratchet face extend ing through and engageable with the cover 16. Wl en this door 33 is raised, it will permit a direct draft from the combustion chamber 20 into the chamber formed rearwardly of the transverse partition 23. The rear of the casing 10 is provided with an outwardly extended portion 35 having a suitable stove pipe connection 36 formed thereon.

When the hrs in the combustion chamber has been properly lit, the door 33 will be dropped, closingthe direct draft between the combustion chamber 20 and the stove pipe connection 36. As soon as this direct draft is out off, the heat and flames from the combustion chamber 20 will be drawn over the baffle plate portions 18, into the control chambers 21, under the heat control doors 24-, into the rear heat chamber 3'7, over the archer capping 30, into the outwardly extended portion 35, through the stove pipe connection 36 and into the smoke pipe. By operation of the control rod 25, the doors 24, in their respective control chambers 21, may be raised or lowered to control the amount of flow of the products of combustion through the control chamhers-21.

The foregoing specification and annexed drawings disclose the preferred embodiment of my invention, but it is to be understood that minor changes maybe resorted to in the commercial adaptation of my invention without departing from the scope of the invent-ion as hereinafter claimed.

What I claim as new is:

1. A stove comprising a base portion having therein a suitably formed combustion chamber; an upper casing being suitably connected and supported from the upper end of said base portion; division walls in said casing extending upwardly in parallel alignment to the side walls of said base portion; the for- Ward portion of each di sion wall extending up higher than the rear portion to form a baffle plate; a transverse partition, the lower edge of which rests on the upper edges of the rear portions of said division walls and abuts the end of said battle plate portions; said transverse partition extending upwardly and suitably connected to the cover portion ofsaid casing; a draft space left between the upper edge of saidbafl'le plate portions and said cover portion; control chambers formed between the outer walls of said casing, said division walls and the respective ends of said transverse partition; a door hingedly connected to said ends of said transverse partition; means provided for raising and iowering said doors to control the flow of the products of combustion from said heat control chambers under the respective ends of said transverse partition; a rear transversely formed chamber into which the products of combustion may enter; and a smoke exit leading from last said chamber.
